Another use case are training sessions where the trainer might need access to the trainee's desktop. VNC session initiated using vncserver. VNC session initiated using vncmanager. This type of persistent VNC session is initiated on the server. The session and all applications started in this session run regardless of client connections until the session is terminated. Access to persistent sessions is protected by two possible types of passwords:.

Open a shell and make sure you are logged in as the user that should own the VNC session. If the network interface serving the VNC sessions is protected by a firewall, you need to manually open the port used by your session in the firewall. If starting multiple sessions you may alternatively open a range of ports.

See Chapter 24, Masquerading and firewalls for details on how to configure the firewall. For persistent sessions, the VNC display and the X display usually have the same number. To start a session with a resolution of x pixel and with a color depth of bit, enter the following command:. The vncserver command picks an unused display number when none is given and prints its choice. See man 1 vncserver for more options. When running vncserver for the first time, it asks for a password for full access to the session.

If needed, you can also provide a password for view-only access to the session. The password s you are providing here are also used for future sessions started by the same user. They can be changed with the vncpasswd command. Make sure to use strong passwords of significant length eight or more characters.

Do not share these passwords. To terminate the session shut down the desktop environment that runs inside the VNC session from the VNC viewer as you would shut it down if it was a regular local X session. If you prefer to manually terminate a session, open a shell on the VNC server and make sure you are logged in as the user that owns the VNC session you want to terminate. Run the following command to terminate the session that runs on display :1 : vncserver -kill Persistent VNC sessions are configured in a single per-user configuration.

Multiple sessions started by the same user will all use the same start-up and password files. After you enable the VNC session management as described in Procedure You will be presented with the login screen. After you log in, the 'VNC' icon will appear in the system tray of your desktop environment. Click the icon to open the VNC Session window. If it does not appear or if your desktop environment does not support icons in the system tray, run vncmanager-controller manually. This is equivalent to a one-time session.

It is not visible to others and will be terminated after you disconnect from it. The session is visible to other users and keeps running even after you disconnect from it. Here you can specify the name of the persistent session so that it is easily identified when reconnecting. The session will be freely accessible without having to log in under user credentials. You need to log in with a valid user name and password to access the session.

Lists the valid user names in the Allowed users text box. Allows multiple users to join the persistent session at the same time. Useful for remote presentations or training sessions. After you set up a persistent VNC session as described in Section After your VNC client connects to the server, you will be prompted to choose whether you want to create a new session, or join the existing one:.

After you click the name of the existing session, you may be asked for login credentials, depending on the persistent session settings. The authentication happens at the beginning of the session; the actual data transfer only begins afterward. The -securitytypes parameter selects both authentication method and encryption. It has the following options:. Anonymous TLS encryption. Everything is encrypted, but there is no verification of the remote host.

So you are protected against passive attackers, but not against man-in-the-middle attackers. TLS encryption with certificate. If you use a self-signed certificate, you will be asked to verify it on the first connection. On subsequent connections you will be warned only if the certificate changed.

So you are protected against everything except man-in-the-middle on the first connection similar to typical SSH usage. If you use a certificate signed by a certificate authority matching the machine name, then you get full security similar to typical HTTPS usage. With X based encryption, you need to specify the path to the X certificate and the key with -XCert and -XKey options.

If you select multiple security types separated by comma, the first one supported and allowed by both client and server will be used. That way you can configure opportunistic encryption on the server. This is useful if you need to support VNC clients that do not support encryption.

On the client, you can also specify the allowed security types to prevent a downgrade attack if you are connecting to a server which you know has encryption enabled although our vncviewer will warn you with the "Connection not encrypted! Contents Contents. Note: Display and port number The actual display or port number you specify in the VNC client must be the same as the display or port number picked by the vncserver command on the target machine.

Figure Name Name of the profile. It will be listed in the main window. Protocol The protocol to use when connecting to the remote session, for example VNC. User name, password Credentials to use for remote authentication. Leave empty for no authentication. Color depth, quality Select the best options according to your connection speed and quality. Tip: Disable encryption If the communication between the client and the remote server is not encrypted, activate Disable encryption , otherwise the connection fails.

Procedure Confirm your settings with Next. Tip: Restart the display manager YaST makes changes to the display manager settings.
